Safety and Dilution are important when using Essential Oils!
I love using essential oils to create a healthy environment in my home. I use them as a preventative measure with my kids, heal minor scrapes and tummy aches, reduce anxiety, and promote peaceful sleep. Keep in mind, essential oils cannot replace medical care for serious illness or injury and safety is very important.
